If an inductor's magnetic material is nonlinear, then the inductance depends on the current passing through it.
This model consists of an inductor with a nonlinear magnetic core, where the small-signal inductance is simulated as a function of current. The model also investigates how the small-signal inductance depends on the DC current.
The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product\'s capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
